Internal USB 3.0 header extension

This EN-Labs U320PMF50CM cable extends a motherboard 20-pin USB 3.0 header by 50 cm. Builders use it when the front-panel USB 3.0 connector cannot reach the onboard header in larger or custom cases. The male-to-female layout preserves the original pinout without adapters.

Passive signal integrity

The extension is a passive copper cable rated for the USB 3.0 specification up to 5 Gbps. It draws no auxiliary power and adds no active components, so thermals and noise remain unchanged from the host port. Backward compatibility with USB 2.0 and 1.1 devices is maintained through the same conductors.

Plug-and-play across legacy Windows

Blue colour coding helps identify the cable inside a crowded chassis. The 20-pin male and female headers connect directly with no driver installation on supported Windows versions including 2003, 2007, XP, Vista, 7 and 8. No software bundle or configuration utility is included or required.

Questions about this item

How do I connect the 20-pin male header to the motherboard without bending pins?

Align the keyed 20-pin male header with the motherboard USB 3.0 header, press straight down until fully seated, then attach the 20-pin female header to your front-panel or drive-bay cable; forcing it at an angle is the step most people get wrong.

Will the blue 50 cm cable jacket or connectors degrade and need replacement?

The passive 50 cm extension has no active components or moving contacts, so under normal case temperatures it does not require scheduled replacement; only physical damage to the connectors or cable would warrant a swap.

What limits sustained 5 Gbps transfers on this 20-pin extender?

The 50 cm length and passive copper conductors are the first bottleneck; signal integrity at 5 Gbps holds within this distance, but longer runs or tight bends would increase attenuation and reduce throughput.
